The Schedule 'referred to in these Letters Patent and making parl: of the To all whom tt lma/y concern;`

Beit known that I, DANIEL H. ROWE, of Pana', in the county of Ghristian,and State of Illinois, have in-v Olothing to Cylinders of Cotton and Woollen-Carding Engines; and I do -hereby declare that the following being had to the accompanying drawings,

part of this specification, inwhich- Figure v1 is a cross-sectionfthrouglr a carding-cylinder having its card-clothing secured upon it. by my improved device. 'Figure 2 is a dia of such cylinder.

vmaking a metricalsection through one end Figure 3 is 'an enlarged sectional vi the fastening.

Figures 4 and 5 are view bar. v

Similar letters oflreference indicate corresponding, parts in the several figures. v

The' object of this invention is to provide for applying card-clothing to the cylinders of cotton and woolcarding engines, in such manner that it canbe held firmly and 'smoothly thereon, and also tightened at ew in detail of s in detail of the fastening- ,The nature of my invention consists vin the employment of one or more tightening-bars, applied tothe card-clothing opposite longitudinal slots or channels formed in the. periphery of a cylinder, and in provid. in'g'such bar or bars with clamping-devices, which are applied upon the inner side of the cylinder, whereby they can be so acted upon as to draw portions of the card-clothing, more or less, into said slots or channels, and .thus tighten this clothing andhold it iirmlyv under any required degree of tension, as will be hereinafter explained.

To enable others skilled in the art to understand' my invention. I will describe its construction'and operation.

In the accompanying drawings-,

` A represents a portion of a carding-englne cylinder,

known manner, with the exception that the strips orA pieces forming the body of this cylinder are secured to its heads, G, so as to leave narrow spaces, c, between them, extending from one end tothe other of the cyl-y inder, and in lines parallel tothe axis thereof, as shown in the drawings. x

The card-clothing, B, is composed of strips, c,having the card-teeth applied in any suitable manner, which strips are laced, stitched, or riveted together along their longitudinal edges, so as` to form a cylinder of cards, which is somewhat larger in diameter than-the linder A, so as to be easily applied'to' or removed t erefrom.

' vrllhe drawings represent the cardgstrips c somewhat wider than the width of the. segments or staves forming the body of the cylinder, so that the seams or -what'wider than thick.

meeting-edges of the'card-strips lie centrally between the edges of the said segments.

O C- represent straight bars, which are equal in length to the card-strips uponthe cylinder, and which are some- The 4strips have spurs, c'c, formed on'thosc edges lying next the cards, which spurs' are arranged at proper distances, and bevelled, as shown in ig.- 3, so that opposite spurs penetrate opposite edges of the backing a, and operate to confine these edges together during the act of stretching the clothing B, and while'it remains on the cylinder under tension. Y 'It is not expected that the said spurs c c will alone prevent the edges of the card-strips from parting, and for this reason thoseedgesare` stitched, laced, or riveted together. The teeth or spurs 'L serveas auxiliaries-to the other: fastening. r j

Atsuitable distances along the spurred edge of the bar C, and at right angles thereto, are short rods, b, having screw-threads out upon themfor receiving clamping-nuts c.

In applying 'the bars C to the card-clothing upon the cylinder A, the rods b are passed between `the edges tof the clothing-strips c, between the cylinder-staves or segments, and through bridge-pieces D, as clearly shown in figs. 1, 2, and 3.- Whenv this is done, lthe nuts c areY secured upon rods b, and set up tightly against the said bridge-pieces, thereby drawing the bars G andportions ofthe card-clothing, more or less, into the longitudinal spaces c, a's shown in figs. 1 and 3. During the act of stretching the card-clothing upon the periphery of the cylinder, by setting 'up the n uts c, as described, the spurs i will penetrate the edges of thecard-'str'ips a, and thus prevent these edges from parting.:

Gardclothing applied to cylinders in 'this manner can be removed, loosened, or tightened at pleasure.

= It can be drawn vas tight as lthe material of which the backing is -made will bear, and it can be adjusted so as to lie smoothly on the cylinders, any inequality in the. clothing being compensated for by setting .up some one or more of the nuts of each griping-bar C more' than others.

Having described my invention, What I claim Vas new, and desire to secure by Letters Patent, isi 1. r.lighteuing-bars G, applied by means of clamp .ing-devices to the card-clothing opposite longitudinal spaces in the peripheryv of a cylinder, substantially as described.

2. rlhe mechanism, substantially as described,or its equivalent, for tightening card-clothing upon a cardingengine cylinder, and which will depress portions of such clothing toward the axis of such cylinder. y DANIEL H. ROWE.
